Here's the trailer image:
And here's some pics of the LA Metro..
Ticket Vending Machine:
The fact that there may be some sort of subway/railway system other than the videos and images of the freight train is not 100% confirmed, I just thought the images were pretty similar. GTA San Amdreas had one subway station on the rail line in Los Santos, I think it would be awesome if they brought this back as a mode of transportation!!!
